James, our master of microscopes, recently received a package from a coral farm in Germany. We’ve explored some of the microscopic creatures and bristle worms that were living and thriving in those packages in previous videos. But today we’re here to focus on the main event: the corals.

once I made a comment here saying that this channel inspired me to try to study biology in college, I passed in one of the best colleges in my country and tomorrow I will have a test exactly about this subject. Thank you so much journey to the microcosm for all the inspiration you guys have given me. hugs From Brazil!
This report makes me happy to hear. I am glad this channel has helped you on your learning path. I wish you a long and enjoyable life.
We are so proud of you!
-James
Congratulations 👏🏾👏🏾👏🏾 . I'm also from brazil and i am doing a course of biology .
Eiiiii parabéns!!! Esse tipo de conteúdo incrível realmente é muito inspirador, eu fico muito muito muito feliz de termos acesso a essas informações apresentadas de forma linda e fácil de entender, e ainda mais feliz de ver que pessoas, inclusive dos nossos BRs vendo e se inspirando!! Obrigada por compartilhar!
[en-us] Ayyyy congrats!!! This type of incredible content really is inspiring, I get really really really happy that we have access to these information shown in such a beautiful and easy to understand format, and even happier that my fellow Brazilians are seeing this content and getting getting inspired!! Thank you for sharing!
I wish I found this channel sooner, then I would have majored in biology maybe
Incredibly interesting biology info: ✔
Stunningly beautiful visuals: ✔
Otherworldly sounding music that fits perfectly with the vibe of the whole thing: ✔
Amazingly relaxed atmosphere and narration: ✔
This might be one of the best channels on youtube :D
Don't forget beautifully-crafted prose writing to describe the science!
So between corals and fungi (lychen), we can conclude that algea will form a symbiotic relationship with just about anything?
What if the next stage in human evolution is artificially forming a symbiosis with algae?
Algae is mostly a good thing in every environment, but in small ponds it can become a real problem because too much algae can end up suffocating the fish within the water
Are you forgetting all of the protists of this channel? A photosynthetic one appears a lot of the time. It is like when you learn about a new protist group your first thought is now "is there a photosynthetic one?" The answer is usually yes, but they are a small subset.
Also leaf sheep (I think is the name)
As I understand it malaria is caused by an algae that adapted to live inside of humans.
Sincere comment alert - I have spent the better part of the past 2 years becoming and staying germaphobic and defending those habits in myself. I’ve been using this channel for a few weeks for doses of calm and interesting in my day, reminding myself of how much i liked microscopes as a kid. All of a sudden, I realized how reassuring it is to understand that there ARE billions of little alive (and otherwise) things in the unseen world that surrounds us. But I have been getting to know them a little better and feeling no anxiety at all. Thank you to this entire team for putting your content out there with so much love and polish!
Surrounds us? How about INSIDE us! 🤯😎
James needs a white light/pol epi-illumination setup so he can look at thick things like corals without having to slice them into thin sections. It might only take a filter cube change since he's got epi-fluorescence already. Even better if we could get him one of those inverted microscopes that make it much easier to deal with large subjects like a macroscopic piece of coral in a petri dish.
There seems to be an error in the video at about 4:10 to 4:30 where hank says (and the caption as well) that the light illuminating the chlorophyll is red but it looks to me like the excitation light is blue or UV, I've never gotten chlorophyll autofluorescence with a red excitation light.
Valid point, the excitation fluorescence start around the green to violet. (Btw if anyone have seen purple fluorescence excitation on coral let me know)
Thank you so much!!! I wish I could get reflected light unit for my scope but it would be even better to get an inverted microscope for stuff like this!
I checked the labels and I don't think there is a mistake with them, I also used a desk lamp. It adds a weird effect maybe that caused the confusion. Chlorophyll shows autofluorescence under any wavelength, maybe you cannot observe it because of the properties of your emission filter.
-James
As a marine aquarist, i appreciate the effort put into this video, great job guys!
Considering the heat and CO2 levels of the early Triassic, I wonder if corals had a different algal symbiosis partner before the Permian extinction.
Even more interesting is considering the heavy sedimentation and rapid climatic changes (a few brief ice ages and then some warmer periods) of the Late Devonian extinction. There was even likely a component of invasive species wiping out more localized forms of many species as Pangaea assembled. I really wonder what those pressures did to corals, considering the vast reef ecosystems of the Paleozoic. The late Paleozoic is so important and so weird.
Given the varied temperatures over the ages its strange that its always just "global warming" being blamed for coral bleaching? As opposed to pollutants?
@@frilansspion
It's not strange, it's outright cap. Any gelologist that doesn't shill the eco-alarmist agenda can tell you this.
@@DinnerForkTongue mmm…figures
I'm glad you finally put coral under microscope, great job. This what I've been trying a little bit on my channel but I'm glad I'm not the only who struggle dealing with them under microscope.
I will take a look in the comment of this video, I'm sure there's must be some good tips!
I work in a store that sells live coral as a photographer, so this is right up my alley!
my goodness how is this so high-quality and why don't you have more views? absolutely amazing content
Very informative, and oh so relaxing and pleasant. You should sell this show to doctor's offices to calm patients.
Till he shows they dying! :-0
Love this! Thanks for all your guys work!
I own pulsating xenia coral and it's my favorite by far because of its graceful movement and interesting features. It's awesome to see it on this show.
This one looks a little sluggish. I think a good saltwater aquarist needs to help James set up a happier aquarium for his little guys to grow and make scum for him to look at.
@@evilsharkey8954 It died the next day! I was very upset!
-James
@@jamesweiss6745 did it have a rough time in shipping? The poor thing looked so weak.
@@jamesweiss6745 NGL, I’m kinda geeking out that THE James replied to my comment. Your footage is amazing. I was a fan back when you just posted silent videos.
I'm a fish breeder, I know you guys have done it already but I would love to send a few samples from some of my tanks, I have shrimp tanks, catfish tanks, live bearing tanks, cichlid tanks..etc
Boosting this.
Well done video as always.
Symbiozomes?! That's gotta be the coolest science word so far!
Always good to watch your videos after a long day😀😀😀
Wonderful! 🙂Great Job.
Enjoyed your video and I gave it a Thumbs Up
i Love Coral and Anything in relation to Deep Ocean life of any kind.
😄👍
Life is just amazing 🙂
I've learned something today, corals are animals not plants. Well, thank you Sir.
Thanks for this video. I knew that coral bleaching was a thing, but didn't know how it happened.
Perfect! 👏🏻💥
Good stuff
Hank does it again 🤩
I asked for coral a while back. Thank you if you took note of that! Maybe you could do a video on the anatomy of micriorganisms? About the organelles and what they do? It was probably already kind of mentioned in passing, I suppose.
I work overnight at a bar. Im going to watch this intently, then put it on repeat and turn the sound off and go to sleep. Thank you
Your channel rocks!
You should make an episode about the identification process of ciliates and how can someone identify the ciliates about their organelles.
Buddy, I legitimately thought that I heard you say “Dino-Flatulence” at the beginning. 🤣🤣🤣
Aren't the coral reefs in Australia currently recovering? Everyone talks about bleaching but not the recovery that's been happening for 2 years straight now
This is a childhood dream!!
I'm brought close to tears watching this footage as an Australian who is only an arms length for 1000's of kilometres of reef currently undergoing their 6th mass bleaching event, the information of which is being withheld as we're weeks away from an election, but has been leaked nonetheless. While many of the organisms covered on this wonderful channel can survive deep space or total desiccation, the reefs around the world will one day solely exist in artificial environments as our oceans acidify and raise in temperature.
On the plus side, you'll be happy to know that Australia's reefs are a tad more sensitive than many others. In fact the reefs of New Caledonia have proved remarkably resistant to pretty much all the crap humans have thrown at them, from mining waste to global warming. Its still devastating to watch as our species trashes the planet like never before, and much will be lost, but life _does_ find a way.
Also of note is that New Caledonia has a myriad of relict species, including some in the reefs. This may not be their first rodeo with regards to mass extinction events. Just a fun little thought I've considered.
@@StuffandThings_ I appreciate your thought however the worst is yet to come.
Sounds like James needs a nice photomacroscope.
A seedbank is one decent contingency plan to save species. But, another would be to sequence and catalog the genomes of our flora and fauna. Surely we'll develop the tech to make "seeds"?
Finally CORAL
Dory!! 💜
You know I'm sitting here wondering why this channel doesn't get tons of more views but then I remember like twice now in last year at least my notification bell got turned off by itself I'm pretty sure but regardless I never get notifications of new vids from this channel I always have to search it out. Maybe y'all should contact CZcams and see if something isn't up
I did not know there was such a thing as soft corals
Hank Green!
I miss my old reef tank.. * sigh *
CORAL!
Por que usaron tts para el audio español???
Does anyone know where that pristine reef at 1:53 is? It’s really heartening knowing there are still amazing places like this
Would love to know this also, that was a good spot, I assume it's around North east of Australia/Indonesia/Salomon (I could be totally wrong)
6:56 here comes the Dory
Just a random question… how come when looking at all these microscopic aquatic organisms, we don’t see them constantly bouncing around due to Brownian motion?
Many organisms will either anchor themselves to something or have something that let's them control their position.
Another could be that they added something like pine sap to the drop to help slow things down.
So I'm not an expert but I think only something the size of a bacteria would be visibly affected by Brownian Motion. Eukaryotes like algae are much bigger.
You need something really small to show Brownian motion. I think they have a video showing Brownian motion in some crystals trapped in a vacual of a diatom or ciliate. You have to remember that in order to show Brownian motion you need something small enough that individual molecules knocking into it will impart an observable change in velocity.
They are too big! Larger particles than 3 microns don't show Brownian motion.
-James
I need to start a coral farm
Starting being a millionaire first.
Dory!!!! I saw her 😂😂
5:37 Oh, I had always figured that the algae live inside the polyps. How do the algae get sunlight for photosynthesis so deep within the coral?
wow
1:36 😂😂😂😂
Octonauts and the barrier reef are talking about the same thing lol zooxanthellae. My 5 year old and I watching the same sort of thing…
Awesome video! One interesting note! I learned that it's not corect to say "dinosaurs that were living in water" douse are actually called Marine Reptiles, not Dinosaurs! :P
0:52
When James gathers samples himself, and they have been fully studied or just take up too much room, he can return them to the same spot he gathered them from. There's no danger to the ecosystem doing this. But with these samples, they came from a different country, and are not in any way close to native to where James is. What will James do with these samples when he is done, or need more room? Will they be returned to the coral farm?
It's not coming directly to the ocean in some random spot, the corals you guys see and more of the time nowadays aquacultured (growing in aquarium) or mariculture (Growing in ocean like a little farm on the shore)
Probably has an aquarium for them or thrown away as those corals are aquacultured for hobbyists, easily reproduce and are not endangered
Ahh nothing I receive can be dangerous to the local environment, there are regulations for that and you cannot ship things without proper permits. I keep the coral samples in my flat with hundreds of other samples! It's just me and my two cats in a three room flat! :)
-James
@@JamsGerms Thanks for replying! I knew there was no chance that you would ever do anything to endanger the ecosystem. The way you care for your "little friends" makes that obvious!
So, If corals and these algaes can form symbiotic relationships like this, is it possible that that’s how mitochondria got introduced to cells? The cells that partnered with mitochondria were more likely to survive since they had the energy?
it’s the endosymbiotic theory of mitochondria which is very well supported by the scientific community.
wow can we edit these genes?
Lisa Frank Corals.... here take my money..
I think you mean that they fluoresce red under blue light?
me acabo de dar cuenta que hay voz en español para el video XD aunque ya me encariñe con la voz en ingles
A mi me confundió un montón....
@@jorgeavalos816 pero esta bien, asi mas gente conoce el canal y las marvillas del micro cosmos
Coincido contigo, la de ingles es más natural, al parecer CZcams esta haciendo pruebas de esta nueva caracteristica con algunos canales como este (al parecer es una voz lograda por inteligencia artificial o algo así) y supongo que una ves que pase la fase ''beta'' esto se hará una caracteristica general, lo cual es muy bueno pues hay mucha gente que no habla inglés y que no va a leer subtitulos y que se esta perdiendo de una gran riqueza de contenido, saludos.
@@Me-sz7yy wow en serio es una voz creada por IA? si es asi esta muy bien lograda, como mucho me llamo la atención que el audio era un poco malo en comparacion con el original pero en todo caso, como dices mucha gente se pierde de contenido debido a la barrera del idioma, esto ayudara mucho a que mas gente expanda su abanico de contenido al que consumir

IT'S A SLIDE CORAL
Hardcoreals.
wait so corals survived the meteor that killed the dinosaurs and the mass extinction? Maybe there is hope for the planet after all
make 1h vids no talking. only soundtrack ❤love u
Technically Zoanthus are something between corals and anemones instead of corals🪸
Yazz
The loss of coral is so scary. The loss of all of the creatures is horrifying to me. Humans are the worst invasive species.
4:48 Please tell me that I don't see micro plastics in this image... 😕
Impossible to say but corals catches tons of mineal surrounding them. I will put my money on little aragonite particle.
@@AquaSplendor I know it can be anything, but it's terrible that I think of microplastics first.
I want to be breeded while the light shines on my body
wut?
Wat
5 months into a 40 gallon.
The spelling of cnidocites seems kind of like cnonsense.
Are you saying that corals are still alive even after expulsing there zo... , hum, there hosts?
So bleached corals are alive?
Thank you
(zooxanthellae)
When the coral bleach it's likely to die(most of the time), in this instance the sps coral he tried are probably a skeleton by now, they do not support very well the stress of environment change.
It's probably a frag aquacultured if people wondering, but I can only assume.
Until they starve to death shortly after.
When the first turn white they are still alive. You are seeing their white skeletons through their transparent flesh. When they yellow a little afterwards they are dead dead. That is their flesh decaying on their skeletons.
The bleaching present in this video is devastating to see.
The best way to help the corals is to change our habit of consummation.
@@AquaSplendor that is very individualist and very narrow. Humans need to consume many things in order to survive. The problem isn't the consuming, it's the what and the how. Pretty much every problem we currently have is a result of ignoring the obviously better but more "expensive" option in favour of cheaper and faster, but not on an end consumer level. End consumers can only choose between the options presented, and the options presented will always be the cheapest and fastest version of whatever that is, even with regards to "high-end goods". The problem isn't consumption, it's profit.
Wait a minute, I thought chlorophyll made plants green! Wouldn't that mean it reflects green light and absorbs most of the red? 4:10
it is green! But it emits red light when you excite it with light energy! We made an episode on autofluorescence before! Check that out! :)
-James
@@jamesweiss6745 I will, thanks!
if we can look at microbes under a microscope and they have no idea that we are there what if there are beings orders of magnitudes bigger than us that are observing us using something other than sight sound touch etc. We'd have no idea that there are there
That Xenia looks a little sluggish. Normally, their little “heads” are opening and closing like crazy. Is it unhappy or just tired? Maybe an expert aquarist can help James set up an ideal environment for his little guys to grow and thrive and produce scum for him to find treasures in.
I wanna be a microbiologist but I'm currently homeless with no diploma. Had to save my mom from dad
You are a good person. Good luck and pursue your dreams
maybe u can by with a 100-200 bucks a nice used microscope someday and start exploring for yourself at least.
i hope the clouds will pass and some sunshine enters your life.

@@slappy8941 why do you think so?
As far as I'm concerned animal rights activists need to get there priorities straight,,, until humanity can tackle the cruelty we still practice on each other we will not address cruelty to animals with any impactful results.... their effort is like pissing up a wall in the way they approach it.. Human desire and willingness to be cruel in general is where the real fight is ,,,,,,you can not tackle animal cruelty with tackling human cruelty.... Pointless effort if your energy is misplaced, its like trying to hammer in a nail with a dinner fork ffs. 👀✌️❤️. ....lack of common sense...
Why Im hearing this video in Spanish???? I preffer the original!
You can change it by clicking the settings on the video. :)
@@jamesweiss6745 Found out already... i guess the feature is new
Why are you saying Cworal? It sounds like you are often deliberately sticking in an extra letter that shouldnt be there?
Sounds like coral to me. Might be the accent?
Another political statement attached to this video from the United Nations. There seem no independents given to content creators.
Yo get a better spanisj narrator
Hate the advertisements and sponsorship, please go back to the old format. I supported the channel back when it was Patreon-only but sadly the advertisements ruined that; why do I need to donate my money when there's a corporation backing it? The main reason I used to watch these before bed was for the relaxing and calm nature of the content, but that has been tainted. The advertainment plugs at the start and finish have been tacky and ruined the true experience of your channel.
More imaginary long ages. :( Why mix the nonsense theories of deep time in with good science?
yeah. satan is still winning. big.
